Well I got a Revenger X Mod, now I'm waiting for the special batteries they are NITECORE IMR 3100 mAh 35A. So far it has been "Rocket Science" and really not so far off with potential explosions and other complexities such as voltage, these batteries are way beyond regular batteries so that's why I'm seeking help from any of ouout electronic wizards. Well that's all, thanks a bunch. Sayonara. PS: I did a search of Rechargeble Batteries(nothing) before posting this thread, per site instructions.
